For sale is your choice of either DIALCO 125-VAC, Series 32, 1-inch Industrial Pilot Lights, left behind in the radio electronics inventory of my late father.  He was an active HAM radio operator for over 70 years, and was a radio and other electronics serviceman for much of his life.  He always kept a generous inventory of spare and replacement parts on hand, for speedy service calls for his customers, available for walk-in customers to his service shop, and handy for his own electronics projects.   All his components were stored in a dry, smoke-free environment. 

My husband did a bit of research for us in my Dad's "collection" of vintage electronics catalogs (right, Dad kept EVERYthing), and here is a some of what he found:

DESCRIPTION:  These are new old stock vintage pilot lights, manufactured by Dial Light Co. of America, Inc., New York, USA, under their Dialco brand.  These rugged instrument panel indicators are an enclosed design, for heavy-duty industrial applications.  Their sockets appear to be high-impact phenolic sockets.  These pilot lights are rated by Underwriters Laboratories for 75 watts at 125 volts service, and feature side-mounted binding screw terminals.  Dialco's Series 32 was marketed as their one-inch pilot light line, designed to fit a panel accommodation hole with a diameter of one inch.  These components include a 120-volt, 6-watt incandescent lamp, with a candelabra screw base and an S6-style bulb.  (The units were tested at 110-VAC and photographed during the test.)  The bulbs are accessible from the front of the panel, by unscrewing the knurled, chrome-plated lens cap, to facilitate ease of lamp replacement.  The lights come equipped with a mounting nut and lock washer, to secure the white nickel-plated bushing in the panel.  Discriminating buyers covet these vintage artifacts for the rugged quality construction.  They are especially desired for restoration of vintage equipment, where OEM components are preferred.  

MANUFACTURER:  Dial Light Co. of America, Inc., New York, USA

COMPANY HISTORY:   The Dial Light Co.of America, Inc. was founded in 1938, with manufacturing operations in Brooklyn, New York, where the company produced aircraft instrument panel light assemblies (pilot lights!) and signal jewels.  The company began marketing its indicator lights under the Dialco brand as early as December 1938.  In 1947, the Dialco brand became a registered trademark of the company.  During WWII, the company supplied components to the U.S. military for aircraft, ships, tanks, etc., under the manufacturer code "CAYZ."  In 1963, the Dialco business was absorbed by Philips, a Dutch company.  In 1990, Dialco products were acquired by the Roxboro Group, through a management buyout.  The business was renamed Dialight in 2005.
